An investigation on the autecological of endemic Iris taochia Woronow ex Grossh. (Iridaceae) distributed in the North East Anatolia region
Özet
This study is subjected to determine the autecological properties of Iris taochia Woronow ex Grossh. (Iridaceae) distributed in North East Anatolia. I. taochia, endemic Irano-Turanian element, is distributed only in the vicinity of Tortum (Erzurum). The chemical and physical analysis have been carried out on soil and plant samples have been collected from six different localities in North East Anatolia. According to the results of plant nutrient analysis, it has been found out that N, P, K, Ca, Na, Mn, Zn and Cu contents are high in above-ground parts during the vegetative growth period and they are high in below-ground parts during the generative growth period. According to the soil analysis, it is obtained that the plant generally prefers sandy-argilloceous- loamy and loamy-sandy type of soil, with a medium alkaline or neutral, non-saline, calcareous in soils in regard of pH. © 2006 Asian Network for Scientific Information.
